Sm2Co17 is a type of rare-earth magnet composed of samarium, cobalt, and other elements such as iron, copper, zirconium, and hafnium. It is known for its high magnetic strength, excellent temperature stability, and resistance to corrosion and oxidation.
According to Stanford Magnets, Sm2Co17 has a SmCo ratio of 2 to 17, meaning that it contains two samarium atoms and 17 cobalt atoms. The energy products of these magnets range from 24 to 32 MG·Oe, which is approximately 192-256 kJ/m.
Sm2Co17 is commonly used in applications that require strong permanent magnets, such as electric motors, generators, and sensors. It is also used in the aerospace industry for various applications, including actuators, sensors, and gyroscopes.
